Vehicle History
Brand Heritage
Renault History Context:	Renault, a historic French manufacturer, was known for its innovative and often avant-garde designs, alongside practical family vehicles. The R21 followed successful models like the R18 and was part of Renault's push into more modern, larger vehicles.
Model Evolution
R21 Introduction:	Introduced in 1986 as a replacement for the Renault 18. It was notable for its aerodynamic 'sledgehammer' styling and innovative features like the PRV V6 engine in the Quadra models (though the 1994 manual likely focuses on the mainstream 4-cylinder variants).
Nevada Variant:	The Nevada (also known as Savanna in some markets) was launched in 1986 as a longer-wheelbase estate version, emphasizing practicality and cargo space.
Facelifts Updates:	Received a significant facelift in 1989, with redesigned front and rear styling, improved interior, and updated engines. The 1994 model year represents a later iteration of the Mk2 facelift.
Production
Production Period:	1986 - 1994 (R21 Sedan/Hatchback), 1986 - 1995 (Nevada).
Manufacturing Locations:	Primarily manufactured in France (e.g., Sandouville factory), but also assembled in other countries under license or for local markets.

Awards & Recognition
Recognitions
Industry Awards:	While specific awards for the 1994 model are not widely publicized, the R21 was generally well-received for its spaciousness and comfort, earning positive reviews from motoring press of the era for its practicality and value proposition.
Ratings
Consumer Reports Context:	Contemporary reviews often highlighted its good ride quality and interior space but sometimes noted reliability concerns compared to Japanese rivals, particularly in electrical systems. This manual is crucial for addressing those potential issues.
